彩色多普勒超声与超声造影对经颈静脉肝内门体分流术后支架功能的评价作用

摘要

经颈静脉肝内门体分流术(TIPS)是目前临床上广泛使用的治疗门静脉高压的有效方法,通过置入支架,将门静脉内血流直接分流到肝静脉中,从而达到降低门静脉系统压力的目的.为门静脉高压晚期合并顽固性腹水、胃底食管静脉曲张破裂出血、肝移植等待及手术不耐受患者提供了治疗机会.TIPS成功的关键在于术后置入支架通畅性的保持,所以TIPS术后监测尤为重要.超声由于具有无创、廉价、实用性强及可重复操作等优点,在TIPS术后监测中具有重要的应用价值.总结了彩色多普勒和超声造影在TIPS术后支架功能评价方面的作用.%At present,transjugular intrahepatic portosystemic shunt (TIPS) is an effective procedure widely used in the clinical treatment of portal hypertension.The blood stream in the portal vein can be directly shunted into the hepatic vein through the inserted stent,which helps to reduce portal vein pressure.TIPS provides treatment opportunities for the patients with advanced portal hypertension complicated by intractable ascites and gastroesophageal variceal bleeding and those who are waiting for transplantation or cannot tolerate surgery.The key to success of TIPS is to maintain stent patency after placement,and therefore,post-TIPS monitoring is of vital importance.As a noninvasive,cheap,practical,and repeatable procedure,ultrasound has an important value in post-TIPS monitoring.This article summarizes the role of color Doppler and contrast-enhanced ultrasound in evaluating stent function after TIPS.
